Which has a more clearly defined shape?

• amorphous solid

• crystalline solid

Why do amorphous solids have an indefinite melting point?

• The particles have a specific structure.

• The particles are bound by less attractive forces.

• The particles are arranged randomly.

• Amorphous solids do have a definite melting point.
